beta-ray-generator

German Architect Andre Broessel believes he has a solution that can “squeeze more juice out of the sun”, even during the night hours and in low-light regions. His company Rawlemon has created a spherical sun power generator prototype called the beta.ray. His technology will combine spherical geometry principles with a dual axis tracking system, allowing […]

A new study shows how much work still lies ahead of us if Switzerland is to do without fossil fuels in the future. There are two possible solutions: storing large amounts of energy in summer and limiting our demand in winter, or generating energy in the 'sunny south' or 'windy north' of the world and transporting it here.

Wind Energy News -- ScienceDaily

Wind Energy Information. From offshore wind turbines to understanding wind turbulence, learn all about using the wind to our advantage. Also, wind testing buildings.

One of the big issues with sustainable energy systems is how to store electricity that's generated from wind, solar and waves. At present, no existing technology provides large-scale storage and energy retrieval for sustainable energy at a low financial and environmental cost. Engineered electroactive microbes could be part of the solution.

Solar panels and wind turbines coupled with energy storage offer a better hope for tackling climate change than trying to capture carbon from fossil fuel power stations, according to new research. New research shows that resources that would be spent on developing and installing carbon capture technologies would be better invested in creating more solar panels and wind turbines and focusing on developing energy storage options to support these instead.

In recent years the US Department of Energy laid out an ambitious plan to grow the US offshore wind sector. Researchers make the case that it might not be as easy as it seems, citing specifically the challenge of supplying rare-earth metals needed to build these offshore wind turbines.

To prevent ice formation on aircraft during flight, current systems utilize the heat generated by burning fuel, but these high-temperature, fuel-dependent systems cannot be used on the proposed all-electric, temperature-sensitive materials of next-generation aircraft. As some scientists search for new anti-icing methods, some have taken a different approach. They've published evidence showing that equipment important in controlling landing and takeoff can double-up as icing control. It depends on plasma actuators.

Temperatures may climb and seas may rise, but the lights (and, undoubtedly, the air conditioning) will still be on in nations with high capacities for wind and solar energy. New research suggests that these electricity systems should work almost equally well in both historical and future European climates despite changing weather patterns.

Hydrogen production based on wind power can already be commercially viable today. Until now, it was generally assumed that this environmentally friendly power-to-gas technology could not be implemented profitably. Economists have now described, based on the market situations in Germany and Texas, how flexible production facilities could make this technology a key component in the transition of the energy system.

Hawaii is famously reliant on imported fossil fuels, for both electricity and transportation. But that’s changing rapidly as the state invests heavily in renewables. Two new bills are now pending in the Hawaii legislature that would codify the 100 percent renewables goal statewide, up from the current mandate of 40 percent by 2030. HB 623 would require...
